BY dj United States Patent ()fiice 2,823,408 Patented Feb. 18, 19582,823,408 MACHINE FOR SUPPORTING AND ROTATING RINGS Ansel R. Meadors,Jr., Greenville, S. C. Application August 3, 1954, Serial No. 447,602 1Claim. (Cl. 15-268) My invention relates to a machine for supporting androtating rings, such as spinning rings.

An important object of the invention is to provide means for holding andengaging the ring at a position eccentric with respect to the ring,leaving the major portion of the ring, internally and externally, freelyaccessible for cleaning or polishing.

A further object of the invention is to provide a machine of theabove-mentioned character which will permit of the quick and convenienthandling of the ring.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this application and inwhich like numerals are employed to designate like parts throughoutsame,

Figure l is a side elevation of a machine embodying my invention,

Figure 2 is an end elevation of the same,

Figure 3 is a plan view of the same, parts broken away,

Figure 4 is a transverse vertical section taken on line 4-4 of Figure 3,

Figure 5 is a longitudinal vertical section taken on line 5-5 of Figure3, parts omitted, and the spinning ring in place upon the lower roller.

In the drawings, where for the purpose of illustration is shown apreferred embodiment of my invention, the numeral designates a table topsupported by legs 11.

Rigidly mounted upon the table top 10, near one end thereof is a block12 having a motor 13 rigidly mounted thereon, including a horizontalarmature or drive shaft 14. The armature shaft has a roller 15 rigidlymounted thereon, and this roller is preferably provided with a resilientsleeve or covering 16, formed of rubber or the like. The shaft 14 isrotated and held fixed against vertical and horizontal movements.

Arranged beneath the shaft 14 and upon opposite sides of the same, arehorizontal shafts 17, the ends of which are arranged within notches 18formed in the sides 19 of a support, casing or carrier 19. The ends ofthe shafts 17 are screw-threaded for receiving nuts 20, which clamp theshafts 17 to the sides 19. The shafts 17 do not rotate with respect tothe casing and rollers 21 are rotatable upon the shafts 17, and ballbearings 22 are preferably arranged between the rollers and the shafts17. The rollers are preferably provided upon their peripheries withannular grooves 23 spaced a suitable distance for receiving the flangesof a spinning ring 24, which is H-shaped in cross section.

Vertical rods 25 are rigidly secured to the bottom of the casing orcarrier 19, and are slidable within vertical openings 26, formed in ablock 27 rigidly secured to the table top 10. A cross-head 28 isconnected with the lower ends of the rods 25 and arranged beneath thetable top, and engages compressible coil springs 29, which engage thetable top 10 and these springs bias the casing 19 downwardly.

Manually operated means are provided to move the casing 19 and lowerrollers 21 upwardly, including a.

vertically swinging lever 30, arranged above the table top and pivotallymounted between its ends at 31, upon a bracket 32, which is fixed uponthe table top. The lever 30 is formed from a bar arranged vertically onedge, and this bar carries a forward extension 33, arranged horizontallyon edge, and formed by twisting the lever bar. The extension is arrangedbetween the bottom of the casing 19 and the guide block 27, and there issufficient space between the extension 33 and guide block 27. Pivotallyconnected with the opposite end of the lever 30 at 34, is a link 35,extending through a suit able opening in the table top 10, and pivotedat 36 to a treadle 37, pivoted at 38, to swing vertically.

The operation of the machine is as follows:

Before the treadle 37 is depressed by the operator, the springs 29 movethe casing 19' and rollers 21 to the lowered position, and there isample space between the roller 15 and the rollers 21 for the operator toinsert the lower portion of the spinning ring between these rollers. Thespinning ring is vertically arranged and its flanges will enter thegrooves 23. The operator now depresses the treadle 37 and shifts it tothe lowered position, Figure 1, and the lever 30 and associated elementsraise the casing 19 and press the lower portion of the ring intoengagement with the continuously rotating roller 15. The resilientcovering 16 of the roller 15 provides a yielding pressure upon the ring.This pressure may be regulated by the amount of downward pressure thatthe operator applies to the treadle. The rollers 15 and 21 hold thespinning ring tates the spinning ring. The rollers 15 and 21 engage thelower portion of the spinning ring, and are eccentric with the spinningring, leaving the major portion of the spinning ring, internally andexternally uncovered and readily accessible to be acted upon by acleaning element or tool in the cleaning or polishing operation. Whenthe cleaning and polishing has been completed, the treadle 37 isreleased and the springs 29 shift the rollers 21 from the roller 15 andthe operator suitably engages the ring by the hand and removes it frombetween the rings 15 and 21.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatvarious changes in the shape, size, and arrangement of parts may beresorted to, without departing from the spirit of my invention or thescope of the subjoined claim.

Having thus described my invention, I claim:

A machine for supporting and rotating a spinning ring or the like havingoutwardly extending flanges to clean or polish the same, comprising asupport having a pair of substantially vertical spaced guide openings, apair of spaced substantially vertical guide rods slidably mounted withinsaid openings, a crosshead arranged beneath said support and spaced fromthe same and secured to the lower ends of the substantially verticalguide rods, compressible coil springs surrounding the guide rods betweenthe support and crosshead and urging the crosshead downwardly, anelongated carrier which is substantially U-shaped in cross section andincludes sides, said carrier being arranged above the support andsecured near its ends to the upper ends of the spaced substantiallyvertical guide rods, spaced substantially horizontal shafts mounted uponthe sides of the U-shaped carrier, said substantially horizontal shaftsbeing arranged in substantially the same horizontal plane and disposednear and above the substantially vertical guide rods, a pair ofrotatable grooved rollers having substantially the same diametersarranged within said carrier and mounted upon the substantiallyhorizontal shafts and held thereby in spaced relation and substantiallyhorizontal, a substan- 24 vertical and the roller 15 ro-' tiallyhorizontal drive shaft arranged near and above and between said rollersand substantially equidistantly spaced from the same, means to mount thesubstantially horizontal drive shaft upon the support and to operate thesame, a spinning ring being adapted to be arranged upon the upperportions of said rollers to have its grooves and its flanges engagingwithin the grooves of such rollers, a friction drive roller arrangedwithin the spinning ring and engaging the lowermost portion of thespinning ring when the spinning ring is mounted upon said rollers, thefriction drive roller being mounted upon the drive shaft to be driventhereby and held against vertical movement, all of said rollers beingarranged in a triangular group and the lower grooved rollers beingdisposed adjacent to the ends of the base of the triangular group andthe friction drive roller being disposed at the upper apex of thetriangular group, the grooved rollers being shiftable vertically withthe carrier member toward and from the drive roller, a generallyhorizontal vertically swinging lever pivotally mounted upon the supportand engaging beneath the carrier member and between the guide rods toraise the carrier member, a pivotally mounted vertically swingingtreadle arranged beneath the support, and an element connecting thetreadle and lever, the springs serving to raise the treadle.
